One possible plot could be that the Joker's chaotic nature influences the female Harry Potter in unexpected ways. She might grow up with a warped sense of humor and a disregard for some of the more traditional magical rules. For example, she could use magic in really out - of - the - box ways inspired by the Joker's antics. Maybe she would be more likely to take risks and face dark magic head - on, rather than following the more cautious approach of the original Harry Potter.
In such a fanfiction scenario, Harry Potter's personality would likely be extremely distorted. The Joker's chaotic and immoral nature would probably make Harry grow up with a warped sense of right and wrong. He might be more prone to using cruel and unethical means to achieve his goals, far from the noble and kind - hearted Harry we know from the original series.
She would be far more unpredictable. The original Harry was quite noble and adhered to a set of moral values. A female Harry raised by the Joker might not have such a clear - cut sense of right and wrong. She could be more likely to play pranks and use her magic in ways that are not strictly 'good'. For example, she might use magic to create chaos in a situation just for the fun of it, rather than to solve a problem in an orderly manner like the original Harry.
Well, if Harry Potter was raised by the Joker, he would probably be trained in a very different set of skills. Instead of learning magic in a traditional Hogwarts way, he could be taught how to be a master of chaos and trickery. His values would be completely different too. He might not have the same sense of justice and good that he has in the original story. The Joker's influence could lead Harry to question the very concept of right and wrong. And his relationships would be strange. He may not form the same kind of friendships as he did in the wizarding world. He might be more isolated or form alliances with those on the darker side of the magical or Muggle world.
Well, in this fanfiction scenario, the very essence of Harry Potter's character would be different. His upbringing by the Joker would mean that his understanding of good and evil is blurred. He might see the wizarding world as a playground for his own brand of chaos. His friends from the original story might become his enemies or he might not have any friends at all. The fight against Voldemort would no longer be a central theme. Instead, Harry could be creating his own brand of mayhem. His magical powers could be used in ways that are not in line with the traditional use of magic in the wizarding world. It would be a completely different kind of story, one that is full of dark humor, chaos, and a lack of the moral foundation that the original Harry Potter series is built upon.
Well, if Harry were raised by the Joker in fanfiction, his personality would likely be a complete contrast to what we know of him. The Joker's influence would make him unpredictable. He might not value life in the same way as in the original Harry stories. Instead, he could be more interested in creating chaos and playing cruel jokes on people, much like the Joker does. It would also change his relationships, as his friends in the original story would probably be very wary of him or even become his enemies due to his new, Joker - influenced behavior.
His magic might develop in a more unorthodox way. The Joker's erratic behavior could lead Harry to use magic in unpredictable situations, which might make his spells more spontaneous but also less controlled.
One idea could be that the vampires, being from an ancient and noble line, teach her unique forms of magic that are different from what she would learn at Hogwarts. For example, they might teach her how to use her magic in a more instinctual and primal way. In this fanfiction, the female Harry Potter could also have enhanced senses due to being raised by vampires, which would give her an edge in her magical adventures.
I'm not sure if there is a specific instance where a 'Joker' would be directly involved in raising Harry Potter fanfiction. Usually, fanfiction is created and promoted by fans themselves within the fan community, not by a character like the Joker.
Well, if we're talking about the Joker from the Batman universe, there's no canonical information indicating he has any knowledge of Harry Potter fanfiction. He's more preoccupied with chaos in Gotham. But in some wild crossovers in fan - created works, he might be depicted as knowing it, just for the fun of mashing up different universes.
